Shear Behaviour Enhancement of Reinforced Concrete Beams By Adding Different Types of Fibers
Aly Gamal Aly Abd-Elshafy,  Mohamed Mahmoud Ahmed,  Abdou Khalaf Mohamed Nagah,  Mohamed Abdallah Ahmed Mohamed
The present study investigate the influence of using different types of fiber together instead of using steel fibers only. Shear strength of fiber reinforced concrete beams (FRCB) was studied in this research project. Three types of fibers were examined: hooked-end steel fiber, glass fibers and polypropylene fibers. The experimental program included six beams with fixed length 2000mm and varied depth, which were divided into two groups A and B. The study investigates the shear strength of FRC beams. The experimental parameters were the type of fibers, effective depth and the presence of stirrups in reinforced concrete beams. The results showed that using steel fibers, glass fibers and polypropylene fibers together as well as steel fibers only increased the shear capacity of the beam specimens more than the beam reinforced with minimum shear reinforcement, reduced the induced deflections and strains and enhanced the load capacity. The result showed the effect of depth on FRC beams and the effect of using stirrups in the shear zone. We can concluded that using different fibers, instead of the use of steel fibers only improved overall shear behavior of concrete.
Keywords- shear strength, experimental work, different fibers, load capacity.
